Subject [jira] [Created] (LUCENE-4482) Likely Zing JVM bug causes failures in TestPayloadNearQuery

Michael McCandless created LUCENE-4482:
------------------------------------------

             Summary: Likely Zing JVM bug causes failures in TestPayloadNearQuery
                 Key: LUCENE-4482
                 URL: https://issues.apache.org/jira/browse/LUCENE-4482
             Project: Lucene - Core
          Issue Type: Bug
            Reporter: Michael McCandless
         Attachments: LUCENE-4482.patch

I dug into one of the Lucene test failures when running with Zing JVM
(available free for open source devs...).  At least one other test
sometimes fails but I haven't dug into that yet.

I managed to get the failure easily reproduced: with the attached
patch, on rev 1397735 checkout, if you cd to lucene/core and run:

{noformat}
  ant test -Dtests.jvms=1 -Dtests.seed=C3802435F5FB39D0 -Dtests.showSuccess=true
{noformat}

Then you'll hit several failures in TestPayloadNearQuery, eg:

{noformat}
Suite: org.apache.lucene.search.payloads.TestPayloadNearQuery
  1> FAILED
  2> NOTE: reproduce with: ant test  -Dtestcase=TestPayloadNearQuery -Dtests.method=test
-Dtests.seed=C3802435F5FB39D0 -Dtests.slow=true -Dtests.locale=ga -Dtests.timezone=America/Adak
-Dtests.file.encoding=US-ASCII

The patch at least isolates the JVM bug even if it's not exactly a
minimal test :)  Somehow the idfExplain method, which
is overridden in this test's BoostingSimilarity, fails to be called
(the super.idfExplain is called instead), which leads to the test
failures.

The failure does not happen if you run this test in isolation.
